Based on the results of preceding researches that the uncertainty perceived
by the private security guards about their roles exerts direct effects on the
business performance of the security industry, it needs to preferentially
examine the degree of authority that the private security guards have. The
suitability of the psychological empowerment criteria for measuring this for
private security guards, however, has not yet been established up to the
present, so it can be said that the validity of the information has not yet been
established. Accordingly, as the psychological empowerment criteria of private
security guards, this research examined the suitability of items, reliability of
items, the level of difficulty of items, and the item goodness of fit from the
viewpoint of the appropriateness of category of responses, and it is summarized
as follows. First, in the self-determinism factor of the psychological empowerment
criteria, Item 11 was found to be an unsuitable item, so it is proper that Item
11 should be deleted when examining the psychological empowerment of
private security guards from now on. Second, the item reliability of the
psychological empowerment criteria was high, so the consistency of the results
is shown even if the data are collected from the other private security guards.
Third, they feel that it is hard to respond to Item 12 while they perceive that
Item 1 is the easiest, and the level of items of the psychological empowerment
criteria is evenly distributed. Fourth, it was established that the 5-point
categories of the psychological empowerment criteria were suitable to the
private security guards.
